muovi-:D BooT-cRIMPER To all whom 'it may concern Be it known that I,WILLIAMB. GLEAsoN, of the borough of Conneautville, in the county ofCrawford,

and State of Pennsylvania, have' invented'a new and useful Machine forCrimping Boots; and I do hereby l declare the following to be a full andexact description ofthe cousin-action and operation of the same, refer'-ence bemg had to the accompanying drawings, and the letters of referencemarked thereon, the same being a vpart of this specification, inwhichlows:

A wooden or iron frame-work, consisting of two uprights, F F, and across-piece, J, is first constructed.

On the inside of the uprights is cut a groove, T T, with the guides G GG G.

In these grooves iit the cogged rack-slides G and D, which are propelledby the gears B B on the shaft A, with the lever E.

These are hung on the uprights, F F, by the brackets H H.

This portion of my invention, together with the crimping-board L, Idenominate the brake.

- Tenoned into the cross-piece J, are the two jaws, I I. These iitloosely in the mortises, so they can be spreadapart at the top.

Fig. 3 shows this part of my invention more perfectly, being a top viewof the jaws, in which I I are the jaws, through which passes a bolt, K,on the end of which is a thumb-screw, U, which is used in giving more orless tension to the spring V.

By means of this contrivance the jaws are made adjustable, so that whenthe machine is being operated they will adjust themselves to thethickness of the leather.

The adj ustability can be varied by the thumb-screw U.

These jaws may be made of wood or metal, as may be desired.

Fig. 2 shows an inside view of one of the uprights, F, together withthat portion of the brake which is thereto attached, i. e., the halfgear B, the rack D, and the guides G G. j

Fig. 7 is a top view of this portion of my invention.

On the lower end of the rack D, in fig. 2, will beseen a mortise, Y, anda similar mortise will alsobenoticed at the upper end of the rack C, iniig. l. y

In these mortises fit the ends of the crimping-board L, seen in iig. l,which, as has been before mentioned,

forms a part of the brake.

Figs. 4, 5, and 6 are sectional views of this portion of my invention.

VThe crimping-board L is made of any absorbingmaterial of suicientstrength.

Projecting from the crimping-board L are the arms Z, Z2, Z3, Z, and Z5,(the latter, Z, is not seen, but its place is indicated by the positionof the letter in iig. 1,) which act as guides to the grab-bars S S andM.

These bars are triangular in shape, as will be seen in the sectionalviews, figs. 4, 5, and 6, and they are also ribbed o r notched.

Fitting over these are the spring-grabs O O O O and Q, which arev-shaped, and are notched or ribbed so as to correspond with thegrab-bars, thereby being4 capable of griping the leather firmly.

a. a. a a a are strips of leather, which are designedy to show theaction of the grabs.

Passing through the grab-bars yS S, at the points marked X X, arethumb-screws P l?, which have their bearings on the crimping-board L.

By means of these screws the grab-bars S S can b'e raised, and theleather be stretched, to suit the oper-' ator.

The grabs marked() can be increased in number, to suit the operator.

The grab Q and grab-bar or block M are held between the arms Z2 and Z3by the bevel-guides on the arms and grooves in the ends of thegrab-blockv M.

This grab is operated by a crank-screw, It, whichis fastened to thegrab-block M.

This screw has its bearing on the top of the crosspiece b, which isfastened to the top of the arms Z2 and Z3 by a mort-'isc and tenon. A

This grab is used in stretching that part of the boot known as theshank, and, as the wrinkles caused by braking and crimping come in thispart of the boot-top or upper, more care is needed than at any otherpoint; and on account of the thinness of the grab-block M,

the leather is drawn closeto the crimping-board L,

. of. my invention, it will be seen that the crimpingboard L iswedge-shaped. This, in connection with the adjustable jaws I I, insures,I claim, a more perfeet brake than has heretofore been in use.

The manner in which my machine is operated is as follows: l

The boot-upper or front which the operator desires to crimp is rstmoistened, as usual, and is then placed in position on the face of thejaws.

`The lever E is then brought down, and thus, by means `of the coggedgears B B and the rack-slides G and D,

the crimping-board L is vforced down between the jaws,- drawing theboot-iront with it. This brakes the boot. The grab Qis then attached tothe corners of the Y shank, and is then screwed up as tight as may bedeemed necessary.

The lever is then raised, and the thumb-screw U may be tightened alittle: then the lever is again forced down.

The grabs O O O O are then attached, and the thumbscrews P P areapplied. This draws the foot and leg of the boot-front to position.

The lever may be then worked up and down a few times, and all the grabstightened.4

' The boot is then crimped, when the crimping-board L audits immediateattachments are removed, and th leather allowed to diy on -the board.

A new crimping-board is attached to the racks C and D, and the work goeson the same as described. l

Herein will be noticed one of the objects of my invention, viz,obviating the necessity of first braking the boot-ont, and then removingit from the brake, and drawing and tacking it on to the crimping-boardby hand, as has heretofore been done.

Each machine is supplied with as many crimpingboards (thereby meaningthe board L, bals S S, block M, and grabs O O O 0 and Q) as thepurchaser may Witnesses:
